1. Set the SR501 jumper to REPEAT TRIGGER, re-apply power, and try again. If necessary, reduce sensitivity to minimize false detection. Be sure to power it with 5V (not 3.3V).

2. This forum is specifically for ESPEasy controlled hardware. So for additional help on your ESP8266 device I recommend contacting the author of the code you are using.
